5. NOTE: A flashing green light indicates low battery voltage.
In this case, place the battery on charge and make sure
that the battery is fully charged before using the smoke
test equipment.

Observe the power indicator lamp on the smoke test
equipment. Make sure that a continuous green light is
displayed.

















6. NOTES:


In some cases it may be necessary to remove the air
cleaner(s) to allow access to the air cleaner outlet pipes.

In some cases it will be necessary to cap one of the
air cleaner outlet pipes. Use the blanking caps supplied in
the kit to cap the open orifice.

Disconnect the air cleaner outlet pipe(s).

7. NOTE: Make sure the smoke test equipment adapter is a
good fit to the air cleaner outlet pipe. This must be an air
tight seal.

Connect the smoke test equipment supply hose to the air
cleaner outlet pipe.
1. Install the appropriate adapter to the air cleaner
outlet pipe.
2. Connect the smoke test equipment supply hose to
the adapter link hose.




















8. NOTES:


The flow control valve must be in the fully open
position.


Smoke is produced for 5 minutes. The smoke test
equipment will automatically switch off after this period of
time.
Switch the smoke test equipment on.











9. Remove the oil filler cap, and observe until a constant flow of smoke is
visible leaving the oil filler orifice. Install the oil filler cap.


10. NOTE: The longer smoke is allowed to exit from a leak, the more
fluorescent dye will be deposited at a leak location.

Using the torch supplied in the kit set to white light, look for escaping
smoke. Alternatively, use the ultraviolet light to look for fluorescent dye
deposits at the source of a leak. www.JagDocs.com

1 Coolant drain plug 2 Torque converter access plug 3 Drive plate 4 Rear cover 5 Main bearing cap 6 Identification mark 7 Front cover 8 Front pulley The main bearing caps are made from cast iron and are cross bolted to increase rigidity. An identification mark on the bearing
cap faces the front of the engine.

At the front of the crankshaft, a tuned torsional vibration damper is incorporated into the crankshaft front pulley. At the rear of
the crankshaft a pressed steel drive plate, with a steel starter ring gear, is installed to transfer drive from the engine to the
transmission. The reluctor ring for the CKP (crankshaft position) sensor is integrated into the perimeter of the drive plate.
The crankshaft seals are located in the front and rear covers.

PISTONS AND CONNECTING RODS



The diameter of each piston is graded and precisely matched to each cylinder bore to help reduce noise. In the vertical plane,
the pistons have a slight barrel form, which helps to ensure a reliable oil film is maintained between the piston and the
cylinder bore. A solid film lubricant coating is applied to both reaction faces of the piston to reduce wear and improve fuel
economy.

A three-ring piston-sealing system is used. The steel top ring is treated with a PVD (physical vapor deposition) peripheral
coating. PVD is a coating technique where material can be deposited with improved properties to ensure good cylinder bore
compatibility and wear resistance. A Napier center ring helps cylinder pressure and oil management, while the three-piece oil
control lower ring is produced from nitrided steel.

The pistons are cooled with engine oil from four piston cooling jets installed under the valley of the cylinder block. Each piston
cooling jet sprays oil onto the underside of the two adjacent pistons, one from each cylinder bank.

The connecting rods are forged from high strength steel. The cap is fracture-split from the rod to ensure precision re-assembly
for bearing shell alignment. There are three grades of large end bearing available, each being color coded. For further
information refer to Engine - 5.0L, Vehicles Without: Supercharger - General Procedures.

1 Inlet camshafts 2 Exhaust camshaft 3 Inverted tooth timing chain 4 Nylon chain guide 5 Auxiliary chain tensioner 6 Auxiliary drive chain 7 Oil pump drive 8 Auxiliary drive camshaft 9 Timing chain tensioner 10 Tensioner lever 11 VCT unit 12 VCT solenoids The lightweight valve train provides good economy and noise levels and is chain driven from the crankshaft.

Double overhead camshafts on each cylinder head operate the valves. For each cylinder head, an inverted tooth timing chain
transfers drive from the crankshaft to the VCT (variable camshaft timing) unit on the front of each camshaft. Graded tappets
enable setting of inlet and exhaust valve clearances.

Each timing chain has a hydraulic tensioner operated by engine oil pressure. The chain tensioners incorporate a ratchet
mechanism, which maintains tension while the engine is stopped to eliminate start-up noise. The chains are lubricated with
engine oil from jets located at the front of the engine block. Nylon chain guides control chain motion on the drive side. VALVE TRAIN

8. CAUTIONS:


Make sure that the area around the component is
clean and free of foreign material.


Make sure the working surfaces are thoroughly clean to
avoid contamination of the sensitive components.


Make sure that the valve grinding paste is kept away
from the valve stem.

Place a small amount of fine valve grinding paste
evenly around the contact face of the valve.
Place the valve in position and, using a suitable
valve grinding tool, rotate the valve back and forth a
few degrees on its seat, using light pressure.
Raise the valve frequently during lapping and turn it
into a new position after a few laps or rotations.
Lap only until a continuous but narrow lapping mark
is visible on both the valve seat and valve face.
Thoroughly clean all surfaces to remove traces of
valve grinding paste from the cylinder head, valve
seat and valve face.
Repeat steps 5 to 8 for the remaining valves.

Installation


1. CAUTION: Make sure the working surfaces are thoroughly clean to
avoid contamination of the sensitive components.


NOTE: Make sure that all the component mating faces are clean.

WARNINGS: Published: 11-May-2011

Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel related components.
Highly flammable vapors are always present and may ignite. Failure to follow these instructions may result in personal injury.


Before any work is carried out on the fuel system, ground the vehicle to earth and maintain the ground connection until
the work is complete.


CAUTION: Before disconnecting or removing components, make sure the area around the joint faces and connections are
clean. Plug open connections to prevent contamination.


NOTE: Tighten the fuel rail high pressure fuel pump fuel line unions and fuel rail crossover pipe unions as it is instructed
in service manual.

WARNINGS: Cleaning

Do not carry out any repairs to the fuel system with the engine running. Failure to follow this instruction may result in
personal injury.


Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel related components.
Highly flammable vapors are always present and may ignite. Failure to follow these instructions may result in personal injury.


If fuel contacts the eyes, flush the eyes with cold water or eyewash solution and seek immediate medical attention.


Place the vehicle in a well ventilated, quarantined area and arrange ' No Smoking/Petrol Fumes' signs about the vehicle.


Wash hands thoroughly after fuel handling, as prolonged contact may cause irritation. Should irritation develop, seek
medical attention.


Do not carry or operate cellular phones when working on or near any fuel related components. Highly flammable vapors
are always present and may ignite. Failure to follow these instructions may result in personal injury.
CAUTIONS:


Before using the cleaning fluid, protect all electrical components and connectors with lint-free non-flocking material.
Make sure that all parts removed from the vehicle are placed on the lint-free non-flocking material.
Make sure that any protective clothing worn is clean and made from lint-free non-flocking material.


Make sure that clean non-plated tools are used. Clean tools using a new brush that will not lose its bristles, prior to
starting work on the vehicle.


Use a steel topped workbench and cover it with clean, lint-free non-flocking material.


Make sure the workshop area in which the vehicle is being worked on is as clean and as dust free as possible. Foreign
matter from work on clutches, brakes or from machining or welding operations can contaminate the fuel system and may result
in later malfunction.

1. Using a new brush that will not lose its bristles, brush the components
being removed and the surrounding area.

2. Using a pneumatic vacuum gun, remove all traces of foreign material.
